Hendrick's winning bid was $1.05 million, for a car that nominally would have a sticker price around $60,000. The money from the sale is being donated to the College for Creative Studies in Detroit, one of the nation's top school for training designers for the auto industry.

It was a busy weekend in Scottsdale for Hendrick. He also bought General Motors CEO Dan Akerson's 1958 Corvette for $270,000. That money is being donated to Habitat for Humanity Detroit's efforts to improve the city's Morningside Commons neighborhood.
